Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before beginning work to avoid burns.

2. Inspect and Clean

Tools Required: Engine degreaser, rags, flashlight.
Inspect the engine bay thoroughly for oil leaks around gaskets, seals, and oil filter.
Clean any detected oil residue with an engine degreaser to better identify future leaks.
Check for burnt oil smell on the exhaust system and note any significant leaks.

3. Address Oil Leaks

Tools Required: Socket set, torque wrench, replacement gaskets/seals.
If leaks are found at the oil filter, remove it using a filter wrench. Replace it with a new filter, ensuring proper torque specifications are followed (typically around 18-24 ft-lbs).
If leaks are present at gaskets (like the valve cover), remove the old gasket and clean the mating surfaces. Apply a new gasket and torque to manufacturer specifications.

4. Oil Change (if necessary)

Tools Required: Oil catch pan, wrench set, funnel, new oil (check manufacturer recommendations for type and amount).
Drain the old oil into the catch pan and replace it with new oil. Ensure the oil level is accurate according to the dipstick.
Dispose of the old oil and filter according to local regulations.

5. Reassemble and Test

After making repairs, secure all components and reassemble anything that was removed.
Start the engine and let it idle. Check for any new leaks or smells. Monitor oil levels after a short drive.
